Application led November 2, 1914. Serial No. 869,775.

.i To all whom it may concern Be it known that I, 7WILLIAM H. Minnie, a citizen of the United States, residing at Chazy, in the county of Clinton and State v of New York, have invented a Acertain new and useful Improvement in Draft-Rigging for Railway-Cars, of which the following is a full, clear, concise, andl exact description, reference being hadV to the accom-A panying drawings, forming a part of this specification.

My invention relates to improvements in draft rigging for railway cars.

The object of my invention is to provide 'a draft rigging for railway cars of simple construction and efficient operation.

In the drawings forming a part of this specification, Figure I is a central vertical longitudinal section partly in side eleyationV of a draft rigging embodying my invention, and showing the normal position of the parts; Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1, and partly in plan View, showing the position of the parts in full buff; Fig. 3 is a cross section taken on line 3-3 of Fig. 1; Fig. 4 is a cross section taken on line 4-4 of Fig. 1; Fig. 5 is a side elevation partly in vertical longitudinal section, showing the outer face of onel of the draft members.

Referring to the drawings, the numerals 6-6 indicate center sills, those shown in the drawings being of the wooden type, to which are secured the draft members 7-'7, each of said draft members comprising a metal arm 8 having near its upper edge an out-turned horizontal flange 9 engaging the lower face 10 of a center sill, the said flange being secured thereto by a plurality of bolts Yl1 passing therethrough and vertically through the center sill to which it is secured. Each arm is also provided with an in-turned flange 12 which engages the lower fiange 13 of a preferably. channel-shaped plate 14 secured to the inner face of the center sill preferably by means of the transverse bolts 15-15 passing therethrough. A draft gear 16 is mounted between the draft members, and includes a casing or shell 17, which shell in preferably construction is Usshaped in cross section, and open along its upper side 18 intermediate the rear, preferably integral, plate 19 and the preferably integral transverse plate 2O connecting the sides of the casing. The forwardly extended lateral portions 22 ofthe shell are adapted to receive the draw-bar 23 between them, the

draw-bar being provided with the usual transverse slot 24 to receivefa coupler key Y25, the key extending through elongated slots 26 in the casingV and passing at lts ends through `the elongated vslots 27 provided in the draft arms. Intermediate its ends, the shell Vis also provided with the elongated slots 28 through which the `key 529 is transversely passed through the casing, the said key 29 extending at its ends through the elongated slots 30 provided in the draft members. A transversely perforated follower 3l is mounted upon the key 29 withinv the casing, and is adapted to be engaged in normal position and in buffing action of the gear by the rear end 32 of the draw-bar 23. Compression resisting elements, preferably springs comprising an outer coil 34 and an Ainner coil `35, are mounted within the casing, the springs being seatedv at their rear end against the plate 19`bf the casing,'and at their forward ends against the follower 31.

In assembling the parts of the draft rigging, the springs, or other suitable compression resisting members, are placed in the casing through the opening on the upper side thereof. 4'The casing is provided near its rear end withpreferably integral, oppositely arranged, outwardly extended lugs 363-36, said lugs being adapted to be received within the longitudinally extended slots 37-37 in the draft arms. The saidv ,slots are each preferably closed at their rear by the web 40, which with the spaced-apart depending web 41 forms an offset portion 42 in the recess 37, which offset portion 42 is adapted to receive the upwardly extended lug 43 with which each member 36 is provided. The engagement of the lugs 43 within the offset portions 42 assists in preventing spreading of the draft 'members in the operation of the draft rigging. The longitudinally extended slots 3737 are each closed underneath by a longitudinally extending supporting plate 45, the ends 46-46 of which enter laterally into the slots 47-47, i extending transversely of each draft mem'- ber, preferably near the ends of the longitudinally extending slot 37 in the same draft member. For further security, the supporting' plates 45 are held in position, and accidental lateral displacement prevented, by

means of the vertical bolts 48-48 which pass therethrough and through the adjacent web 49 of the draft arm. lhe draft arms in preferable construction abut at their rear ends against the front face 50 of a channel tie member 51, and at their forward ends are secured to the end sill 52 by the vertical bolts 53, which are also employed to support the draw-bar carry-iron 54.

From the foregoing description, the operation of the draft rigging will be understood.

On forward movement of the draw-bar, the coupler key engages against the forward ends of the slots 26 in the casing, thus drawing the casing forward, the key 29 Vbeing stopped against the forward ends of the slots 30 in the draft members and holding the follower 31 against forward movement, between which follower and the rear end 19 of the casing 17 the springs 34 and 35 are compressed. The members 36 at the rear of the casing slide forwardly in the slots 37 guring the forward movement of the draw- 'On rearward movement of the draw-bar, the coupler key moves rearwardly in the slots 26 in the casing and the slots 27 in the draft arms, the casing is stopped against rearward movement through the abutment of the lugs 36 of the casing against the rear ends of the slots 37 in the draft members; the rear end of the draw-bar in its engagement against the follower 31 forces the said follower rearwardly within the casing, the key 29 meanwhile sliding rearwardly in the slots 28 through the casing and the slots 30 in the draft members, thus compressing the springs withinthe casing between the follower 31 and the rear end of the casing.

It will be clear that in mounting the draft gear between the draft members, the plates 45 are removed, the shell lifted to its position between the draft members with the lugs 36 thereon mounted in the slots 37, which are then closed by laterally sliding the plates 45 into position, closing the lower edge of each of the slots 37, and then placing the bolts 48 into position to secure the plates 45 against accidental displacement.

I claim:-
